I’m currently a computer science student at the University of Applied Sciences in Rapperswil. I’m mostly interested in the technologies behind the pretty user interface =). Like databases, application-modularity, concurrency and so forth.

Saving & restoring undo stack — good or bad?Yes, I really love this feature in IntelliJ IDEA. And I think a lot of application would benefit from similar features. Lot of web-application provide similar functionality. For example the google-docs. (ok it doesn't store it so often)
